We recently migrated from 7.2.x to 8.0.0 FOSS. The migration itself seems to have been very successfully, but there is one thing that came up so far:

At least three out of ~100 Users report having "a bunch of calendars that look broken". After a closer look, it turned out, that, indeed, there were lots of calendars added to their accounts. I would love to know, if there's any simple way to get rif of them. If anyone knows, where they came from, that would be even more tremendous.

I can view these things with a call to zmmailbox (zmmailbox -z -m ---user's e-mail--- gaf). I added the full (but slightly redacted) output below.

after switching to zimbra user, we use zmmailbox to get a list of all the folders (gaf) for a given account. I store this info in /tmp/gaf.txt.
I then process the file to cut away everything but the folders column. Afterwards i'll filter for the uuids (slash + 36 characters hex+dashes). I'll add deleteFolder in front of every row and put that into a textfile of its own. You can then review that textfile before running it in the last step.
In the end i pipe those commands into zmmailbox.

I should mention that this is a destructive change. Please make sure you don't have anything in thos UUID-Calendars.

Reason: found a more elegant solution that runs much quicker.
